Reducing Dorsal Hump Recurrence Following Push Down-Let Down Rhinoplasty

Abstract

BACKGROUND: Hump recurrence is a commonly encountered problem following dorsal preservation (DP) rhinoplasty when surgeons are learning the procedure. OBJECTIVES: The aim of this paper was to compare the different methods for the prevention and treatment of dorsal problems following DP surgery. METHODS: One hundred and fifty primary rhinoplasty patients were included in our study. Their noses were classified in terms of both hump shape (V- or S-shaped) and height. All patients had a DP rhinoplasty by either a push-down (PD) or a let-down (LD) technique. The PD method was used for humps <4 mm and the LD for humps >4 mm. Follow-up evaluations were made with physical examination and photographs at 1 week, 3 months, and 12 months. RESULTS: Mean follow-up was 12.68 [1.78] months. Seventy-eight humps were V-shaped and 72 were S-shaped. PD was used for 67 cases, LD for 83 cases. Eight patients (5.3%, 8/150) had a visible dorsal hump problem after DP surgery. Based on their preoperative hump shape, 3 cases were V-shaped and 5 were S-shaped. All recurrent cases had a preoperative hump deformity >4 mm. The revision procedures were as follows: 4 patients had a PD procedure, 3 had a LD procedure, and 1 patient was treated by classic open resection rhinoplasty. CONCLUSIONS: There is a correlation between preoperative hump height and eventual hump recurrence. The complication rate can be decreased with additional technical maneuvers and proper patient selection.
